This condo is exactly as described/pictured, and a fantastic choice if you're looking for a quiet, private stay during your time in Bangkok. The place was spotlessly clean when I arrived, and Helene provided everything I could have needed for my month-long visit. She was also incredibly quick to reply to any questions I had.
As others have noted, the condo is a bit of a distance from the traditional "touristy" parts of Bangkok, but I found that to be a definite postive; it was an escape from the chaos and noise of the city. Besides, public transport is close, and there are motorbike taxis waiting right on the corner to take you anywhere for a very reasonable price. As with anywhere in BKK, you don't have to wander too far to find traditional Thai street food, and Show DC and some other shopping centres are nearby if that's your cup of tea. The condo is also just a short walk from RCA, which is full of clubs, bars and restaurants. And there's a 24-hour convenience shop located within the condo complex that makes life very simple.
Overall, 10/10! When I come back to Bangkok, I'll be staying here if it's available.
